Until recently I used only CentOS_5/i686 and saw no noticeable picture

corruption - small transient rectangles - when shrinkage has been applied.
So it seems to me that tcrequant is *not* broken on all platforms and I
would not like it to disappear globally unless, of course, there is a
reliable and effective alternative.
I've also had my share of problems with tcrequant.

I thought it might be useful to add a note that the download from the
company that posted the initial version of this requantiser now has a
source date for 'main.c' of January 2008. I'm not confident that I could
rebuild it immediately for my system, but others may not have seen it. It's
GPL. http://metakine.com/products/dvdremaster/modules.html
Compilation on a x86_64 system worked for me (with minor tweaks,
seems they aren't prepared for the system to be anything but a ppc or i386).
It does seem to work!
Yes: I have now briefly compared the 'new' code with tcrequant and it
looks as if there are probably changes in the algorithm; certainly much
of the code is different. It is, of course, initially for a Mac.
I suspect that the functional part of the 'new' code is essentially the
same as that used in vamps, in which it has been given a wrapper
intended for dvd shrinkage under linux. I now have that installed under
fc10/x86_64 and have so far shrunk one VOB file by a factor of 1.5
without any obvious unwelcome artefacts - or, AFAICT, 'DEMO' features!
